.To lallfuihmn imag/concern:

Be it known thatwe, Moses CHANDDERand J onN W. CHANDLER, of- East'Corinth, in the county of Penobscot and State of Maine, have invented` a new and ImprovedGombined Cultivator and Potato-Diggeryand we dohereby 4declare that the lfollowing is afull, clear, and

exact description thereof, which will enable others .skilled in 'the art to make and use the same, reierenceabeing had' to the accompanying horizontal section' of the.same,ta ken in thel linew` .`[1`ig. 2. Similar letters of reference indicate like oruse of two adjustable blades or cnltivators,

' in connection with a screen and shares, all arranged to 'operate in the manner hereinafter set forth. l

A represents thebeam ofthe implement provided with two 4handles,.B B, and. a cross-bar, O at itsrear end,ft he latter having two oblong slots, a q, made in it longitudinally near each end, as shown inFig. 1.

D D are two standards', which may be of `castiron. These standards have screw-rods b at their upper e'nds which pass upthrongh the slots a in the cross-bar C, and have nuts c on them abovethe slots forthe purpose of secur-V ing the standards firmly to the cross-bar. The

standards D D at-their lower partsproject angularly forward, as shownatd in Fig, 2, and` these lower parts have obliqueiianges e projecting from their outer sides, as shown clearly in Fig. 3, and tojthese ianges. blades' or* cultivatorsnE are attached, o-ne to each, by pivotbolts f. The shapeof the blades or cul tivators is shown clearly in Figs. 2 and 3, and they have a ila-ring or 4oblique position relatively with each other, as shown in- Figs..1 -and 3, the front. ends of the blades orcultivators being nearer to each other thairjthe opposite` ends: "These blades or cnltivators may be secured 'in a more for less-inclined or raking positionl by means of nutsc on the rods b of the .standards D.

\ F F represent two screens,whi'ch are formed by'a series of teeth or lingers 'i atthe rear ends of `plates Gr,y which serve as shares.. These 1 shares are secured by bolts j' to the lower part 'ofthe standards D D, andra space, k, is allowed between the shares, 'as shown in Fig. 43. `The teeth ortngers i have what may be termed a lowest.`

The operation is as follows The implement fan-like position, theirlfront edges being the is drawn along so that the blades or cultiva-- tors E E will scrape or take od" the sides of the hills or drills, while theshares G and Vscreens 'attached to' them, but'loosened from the soil.

The space k-between the shares G admits of obstructions passing between vthe shares which mightgather'upon them. ',lheV chief advantage of` this-implementis fthat, it digsthe potatoes'without detaching them from the tops, thereby effecting a great savingof time in gathering the potatoes, asl

`the tops are grasped by the operator and the potatoes shaken oft' into the basket. Another advantage is that the implement may be usedl as a cultivator at any time for pulverizing the .W e claim .as new and desire to secure by Letters Patent- 1. Theoblique blades or cultivatorsfE E, in

com bination.; with the shares G Gr' and screens F F, allarranged ,to operate substantially as and for the purpose set forth.'
